SHAFT-BEARING.

SPECIFICATION forming part of Letters Patent No. 667,037, dated. January29, 1901.

Application filed August 12, 1899.

T0 at whom it may concern:

Beit known that we, CHARLES RICHTER and RICHARD T. ESCHLER, citizens ofthe United States,residing in the city and county of Camden, State ofNew Jersey, haveinvented'a new and useful Improvement in Shaft-Bearingsfor Traction-Motors, which improvement is fully set forth in thefollowing specification and accompanying drawings.

Our invention relates to an improved construction of a shaft-bearing fora traction-motor, wherein provision is made for cushioning and reducingto a minimum any excessive vibrations, means also being provided forcarrying wires and oiling devices in said shaft.

It consists of novel details of construction, all as will be hereinafterfully set forth, and particularly pointed out in the claim.

Figure 1 represents a sectional view of a shaft-bearing for atraction-motor embodying our invention, the section being taken on linea: 00, Fig. 2. Fig. 2 represents a section on line y 3 Fig. 1. Fig. 3represents a section on line 2 a, Fig. 1.

Similar letters of reference indicate sponding parts in the figures.

Referring to the drawings, A designates a hanger or bracket, in which iscontained the box B, the same consisting of the sections C and D, whichare held in assembled position by means of the bolts E or other suitablefastening devices, said box being provided with polygonal recesses F,which are terminated by the Wall G, said recesses being juxtaposed, aswill be understood from Fig. 2, and having seated therein a ring orcushion H, of rubber or other resilient material, said ring being ofpolygonal shape and having its sides of the same contour as saidrecesses and adapted to receive the polygonal-shaped end J of the shaftK, which latter is provided with a recess or slot L therein, the extentof which can be understood from Figs. 1 and 3, said recess or slotcarrying oiling devices M and wires M N designates a case-hardenedsleeve fastened to the shaft K by a suitable fastening device P, thehead of which is flush with the periphery of said sleeve. It will ofcourse Scrial No. 726,992. (No model.)

be evident that any number of fastening devices may be employed.

Q designates a hardened sleeve, which is fastened to the hub R of theWheel S by means of a suitable fastening device T. It will of course beevident that any number of fastening devices may be employed.

U designates a spring or other tension device bearing upon the member Cof the split box B.

The operation is as follows: The shaft K, which is stationary, is heldin fixed position by the engagement of the polygonal end J with thesurrounding rubber ring or cushion H, which latter can be compressedbetween the box-sections to the desired extent by tightening the boltsE, as is evident, wherefrom it will be seen that a simple and effectivecushioning device is provided, provision being at the same time made forpreventing rotation of the shaft K, said device being readily accessiblefor the purposes of inspection and repairs and not liable to get out oforder. The case-hardened sleeve N, which is rigidly secured to the shaftK, serves as a bearing for the wheel S and the hardened sleeve Q, whichis secured thereto and rotates in unison therewith.

It will thus be seen that by the foregoing provision is made forreducing jars or concussions to a minimum and means are also providedfor furnishing a cheap and efiective bearing.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

The combination of a split box, means for holding the sections of saidbox in juxtaposition, said sections being provided with a polygonalrecess, a resilient ring held in said recess, and a shaft having apolygonal end seated in said ring, whereby rotation of said shaft isprevented and vibrations are reduced to a minimum.
